SMITH, F BROCKTON, MASSACHUSETTS, ASSIGNOR TO FIRTH-SMITH COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS IETHOD OF AND APPARATUS FOR OPERATING ON SPINNING FRAMES AND OTHER MACHINES Application filed December 31, 1928. Serial No. 329,422.

It has been a serious problem in spinning mills to prevent the formation of so-called bunches, slugs or gouts in the yarn which are caused by the accumulation-of minute particles of loose fibers, invisible fly, lint and dirt on the work during the spinning operation. These bunches materially impair the quality of the yarn and it has been estimated that they cause from twenty to thirty per centum of loom stoppages. To overcome this difiiculty it has heretofore been proposed to traverse a downwardly directed stream of air over the machines of each row successively, the pressure of the air being sufficient to force such particles away from the work and toward the floor-in such a manner as to prevent adhesion or accumulation until after they pass beneath the work.

In accordance with the present invention in its preferred embodiment, the desired result is accomplished by creating a stream of air directed upwardly or away from the ma: chines so as to cause the particles to be drawn or carried therewith, and preferably collecting the particles in a suitable receptacle. which travels along with the stream of air over the machines. Where the particles are thus collected in a receptacle from which they may be easily removed and destroyed, the entire room may be maintained, substantially free of such particles. Also, in connection with said upwardly directed stream of air, a stream of air may be directed downwardly over the machines, preferably at the rear of P the upwardly directed stream so that in case any fine particles are not removed by the up wardly directed stream they may be blown or carried toward the floor by the downward ly directed stream. I

These and other features of my invention will be clearly understood from thefollowing description and accompanying drawing,'in

which: e

* Figure 1 is a side View, partly in section, of an apparatus which is adapted for use in carrying out my improved method;

Fig. 2 is a frontend view of the same i is a diagrammatical plan view illustraiing the manner in which the apparatus may operate upon a plurality of rows of spinning frames or similar machines; and

I Fig. 4 is a diagrammatical side View of the apparatus while operating upon a spinning frame.

- The apparatus illustrated in the drawing is particularly adapted for use.in operating upon spinning frames, indicated at 2 in Fig. 3, which are commonly arranged in the spin- ;ning room in rows with the frames of each row arranged end to end. As shown in Fig. 3, the apparatus is provided with an endless track 4 which extends centrally over the machines of each row, and is spaced a suitable distance above the machines. The apparatus is further provided with a carriage 6 mounted to travel along the track continuously by power-operated means so as to pass succes sively upon the machines of each row and over the several rows of machines successively at predetermined intervals. The carriage 6 is suspended from the track by means of wheels or sheaves 8 which ride on the track. A fan or blower casing 10 is secured to the underside of the carriage. A bracket 12 is secured to one side of the casing 10 and an electric motor 14 is mounted on this bracket. This motor is energized through connection with trolleys 16 carried by the carriage, the trolleys engaging trolley wires 18 suitably supported beneath the track. The carriage is propelled along the track by means. of a belt or sprocket chain 20 which passes-over ulleys or sprocket wheels on the motor shaft and the shaft on which one of the carriage wheels 8 is mounted." A fan 22 is secured on one end of the motor shaft within the casing 10. A suction nozzle 24 is in communication with the interior of the fan casing through a central opening in one side of the casing. This nozzle is inclined downwardly and forwardly and has a wide flaring mouth arranged'substantially centrally of the carriage 6 so as to draw a wide and thin stream of air upwardly.-

The draft side of the elbow 25' into a casing 26 detachably secured to the elbow. A dust bag 27 is suitably s'up ported within the casing. The casing 26 is provided with one or more'nozzles 30 n its fanleads through an Y lower portion for directing the air which is impelled through the dust bag 26 downwardly.

The apparatus is so supported as to position the suction nozzle 24 and the draft nozzle 30 suitable distances above the tops of the machines to be operated upon, that during the travel of the carriage along the track the nozzle 24 will direct a stream of air upward- 1y so as to tend to draw dust and other line particles from the machines and the atmosphere above the machines and deposit them in the dust bag 27, and the nozzle 30 will direct a stream of air downwardly over the machines under sufficient pressure as to blow any such particles ren'laining on the machines and in the atmosphere above the machines, toward the floor. The dust bag may be emptied from time to time and the contents destroyed.

It will be apparent that in the operation of my improved apparatus in carrying out my improved method, effective and uniform cleaning of the machines and the atmosphere above the machines may be accomplished, and

the entire room may be maintained substantially free of dust and other fine particles.

As will be evident to those skilled in the art my invention permits various modifications without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

1. The method of operating on spinning frames and other machines arranged in rows, which comprises creating an upwardly directed current of air, traversing the current of air in an endless path successively overthe machines of the several rows so as to draw dust and other fine particles from the machines, and collecting said particles in a receptacle 2. The method of operating on spinning frames and other machines arranged in rows which comprises creating an upwardly directed current of air, traversing the current of air in an endless path successively over the machines of the several rows so as to draw dust and other fine particles from the machines, collecting-said particles in a receptacle, directing air downwardly over the machines and toward the floor, and traversing the downwardly directed air in said endless path and at a distance to the rear of said upwardly directed current of air.

3. The method of operating on spinning frames and other machines arranged in rows,

. which comprises directing a current of air upwardly to a point spaced a distance above the tops of the machines and then downwardly over the machines and toward the floor, traversing said stream in an endless path successively over the machines of the several.

rows so as to cause the portion of the stream which is directed upwardly to draw dust and other fine particle from the machines and the portion of the stream that is directed downwardly to blow dust and other fine particles from the machines and from the atmosphere above the machines toward the floor, and separating the' dust and other fine particles from the stream.

4. Apparatus for operating on spinning frames and other machines arranged in rows having. in combination, an endless track, a carriage mounted to travel along the track, a blower, a motor mounted on the carriage, connection.-; between the motor shaft and the blower for driving the blower, connections between the motor shaft and carriage for driving the carriage along the track, and a casing enclosing the blower having a nozzle -in communication with the vacuum side of the blower for directing a current of air upwardly, and a nozzle in communication with the draft side of the blower for directing air downwardly, and a dust collector between the la st mentioned nozzle and the blower for separating dust and other fine particles from the air before the air passes through this nozzle.
